The superallowed decay of 35Ar: A persistent anomaly Academic Article uri icon


  • The branching ratio for the decay of 35Ar to the first excited state in 35Cl has been measured to be (1.340.08)% with the ISOLDE on-line isotope separator. Combining this result with previous data leads to the value (98.280.06)% for the branching ratio of the ground state (superallowed) transitions. This does not resolve the apparent anomalousness of the derived Cabibbo angle for this transition, which now stands at v < 0.10 with a 95% confidence level. 1979.
